Am I stank?

My boyfriend and I have been together 2 years and are extremely kinky/ explorative in the bedroom there’s nothing we haven’t tried. I remember him saying when we first got together that he loved giving head. He’s amazing at it it’s the best oral I’ve received and I want more. However he’s only done it twice in 2 years. Is there something wrong with me? It’s got me thinking I stink down there but we do things with my booty and to me that probably stinks more than vagina. Any tips on how to bring it up to him jokingly and see what’s wrong? He gets awkward and avoids the question if I straight out ask.
